Thank-you Oron, of course it is. I hate it when my brain forgets something I know so well!
ezeiza, I was told when I bought it, that this plant was Solanum lacinatum! I knew it wasn't, but did not know what it was, until I saw it on John's thread on this forum. It has only been planted a few months, but has doubled it's size in that time.
I notice that in the hottest part of the summer, it drops it's flowers around lunch time, but now that it is cooler, it holds them all day.
